摘要

常规电流互感器在电力系统中的监测和保护作用是不可忽视的。虽然CCT已经被广泛使用了很长一段时间,但CCT所面临的许多问题和问题,如浪涌电流、饱和、电流互感器比等,使其使用受到很大的限制。cct中出现的问题吸引了研究人员和保护工程师对基于光电磁的新仪器技术的兴趣。在此基础上,提出了一种遵循法拉第电磁学定律的光电流互感器模型。OCT的使用将解决cct所面临的几乎所有问题。因此,这种新型OCT可以很容易地取代cct,用于保护和计量目的。这里提出了使用运算放大器的OCT仿真模型,只是为了激励保护和设计工程师,特别是巴基斯坦的工程师,采用OCT的新技术来代替CCT测量电流。除了解决所有与CCT相关的问题外,OCT还将使电能质量更好。从OCT可以获得三种类型的输出:低能量模拟输出(LEA),高能量模拟输出(HEA)和数字输出。由于采样率的限制,数字输出很难利用更宽的带宽选项。为了利用OCT的所有优点,这里将使用低能量输出信号来满足这里的仿真要求。在所需的OCT模型开发完成后,将纳入仿真结果,以证明CCT可以被OCT替代。

Modeling and simulation of optical current transformer using operational amplifiers
The importance of Conventional Current Transformer (CCT) for the monitoring and protection in power systems is not ignorable. Although there has been an extensive use of CCT for a long time but a lot of problems and issues such as inrush current, saturation, current transformer ratios, etc. faced by CCT make its use quite limited. Issues arising in CCTs have pulled the attraction of researchers and protection engineers towards a new instrument technology based on Opto-Electromagnetics. An Optical Current Transformer (OCT) model based on the simulation has been proposed here which follows the Faraday's law of Electromagnetics. The use of OCT will resolve almost all issues that were being faced by CCTs. So this new designed model of OCT can replace easily the CCTs for both the protection and metering purposes. This simulation model of OCT using operational amplifiers is being proposed here just to motivate the protection and design engineers especially in Pakistan to adopt the new technology of OCT for the measurement of current in place of CCT. In addition to resolving all issues related to CCT, OCT will also make the power quality better. Three types of outputs can be obtained from an OCT which are: low energy analog output (LEA), high energy analog output (HEA) and digital output. Due to sampling rate limitations involved, a digital output is hard to use to avail the wider bandwidth option. To use all the benefits of an OCT, a low energy output signal will be used here for the simulation requirement here. After the required OCT model development, simulation results will be included to prove that CCT can be replaced by the OCT.
